3.7.5. AT+CTZU - Automatic Time Zone Update
Set command enables/disables the automatic time zone update via NITZ.
AT+CTZU=<onoff>
Parameter:
enables/disables the automatic time zone
update via NITZ
The command +CTZU is the ETSI standard equivalent of Telit
custom command #NITZ (for the date and time update
functionality).
Despite of the name, the command +CTZU enables automatic
update of the date and time set by +CCLK command (not only time
zone). This happens when a Network Identity and Time Zone (NITZ)
message is sent by the network.
If the automatic date and time update functionality has been
enabled by +CTZU or #NITZ (or both), NITZ message will cause a
date and time update.
